Notes. Column 1 contains the id assigned to the variable star, Cols. 2 and 3 correspond to the right ascension and declination (J2000), Col. 4 shows the epoch used, Col. 5 shows the period, Col. 6 contains median of the data, Col. 7 shows the peak-to-peak amplitude in the light curve, Col. 8 contains the number of epochs and Col. 9 shows the classification of the variable. The numbers in parentheses indicate the uncertainty on the last decimal place of the period.
